    Interesting ...

    Are cold cracks covered under warranty?

    No. Cold cracks are caused by subjecting the hull material to stress beyond its design limitations and are thus excluded from warranty coverage.

    The manufacturer of Royalex does not warranty the material to the canoe molders for this issue. It is their position that it is a material limitation, not a material defect, that makes the material prone to cold cracks. Given all the studies and effort that has been dedicated over the year to solving this issue, that position is justified.

    How are cold cracks repaired?

    In short, kevlar or fiberglass patches are placed on the inside of the canoe and embedded in epoxy adhesive. It is not a particularly complex process but can be a bit messy.
